Specification forming port of Letters Patent No. ihhd,2fhi, dated April 8, 1879; application filled J nly 12,

To all whom it may concern..-

iBe it known that I, HENRY BURK, of the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Presser-Foot Attachments for Sewing-Machines, of which the following is n specificotion:

The object of my invention is to provide improved moons for fecilitcting the sewing of it stay or strip upon or over either at seem or plain snrfece on a shoe, orticie otherness, or other manufacture of leather or enologons material in which stn-ys or strips are required.

To this end my improvements consist in the combination, in n resser-foot, of e grooved rotating resser-roller and e stotionnry sto guide, as hereinafter more fully set forth.

In the accompanying drawings, Figure 1 is e view, in perspective, of my improved attachment; Figs. 2 and 3, side views, inelevetion, of the some; and Fig. 4, it view in perspective, showing the cherocter of the work on which the device is employed.

The arm A has at one end the ordinory socket o, for attachment to the preseer-her, end at the other e projecting stud or pin, upon which at resser-roller, B, is mounted. so as to rotate freely, This presscr-roller is substentiaiiy similar to those ordinarily employed in sewing leather, saving in the respect that its periphery in circumterentiolly grooved or recessed, as shown, so as to beer npon the work at its sides, instend oi, as is nsnei, uniformly across its face, and thereby to correspondingly mold or form the strip or etey so that it shall he convex ct its center and closely applied at ite eides, Where the stitching is loceted, to the materiel to which it in to he united, thus relieving the etrip from friction upon the seem, as well as providing space for the insertion oi o cord beneath the strip, when desired.

A box or trough shnped stationery guide, C, open nt hottom, is secured by moons off on upwardly-projecting arm, 0, formed open it, to the projecting end of the stud on whieh the presser-roiier E rototee, in iine trith,nnd es ciose ns procticehlo to, snid preeeerroller, the function oi the guide being to proneriy direct and present the strip or etey to the preeeen roller end needle.

The strip mzty he led to the guide from at ease or box in which it is coiled, or item eny other snitehle receptiicle, which need not he here described, as it forms no'pnrt oi any present invention.

The width or? the guide, are weil es thet oi the PI'GESGT-KOllfit, is, of coerce, made conformnhie to that of the etrips operated open.

A cord-guide, 0, consisting of on eye or ioop of Wire or sheet motel, mey he honored upon the front end of the guide U, for the purpose of lending a cord beneoth the strip or stey when the some is deeired to he insorted.

I em ewnre that the nee of o hwy-guide, in

connection with e preesenfoot, is not new,

and do not,therefore, broadly cieim eoeh device.

I cinim as my invention and desire to secure by Letters Potent- The combination, in o preseer-i'oot', of e grooved nresser-rolierend o stetionery stoy guide, the cotnhinntion being end opereting snhstnntieliy on end forthe purposes set forth.
